PLOW-CLEVIS.

EPECIPICATION forming part of Letters Patent No. 344,245, dated June 22, 1886.

Application filed January 21, 1886.

To all whom, it may concern:

Be it known that I, HOWARD H. BUTLER, a citizen of the United States, residing at Oanton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Plow-Glevises; and I do hereby deelare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon, in which Figurel is a perspective view showing the clevis properly attached to aplow-beam. Fig. 2 is a detached view of the locking block or plate. Fig. 3 is a perspective view of the clevis-link, showing the crow nhead and plowbeam removed; also showing a portion of the double-tree clevis. Fig. 4 is a top view of the clevislink, showing the double-tree clevis properly located on the forward end of said clevis-link. Fig. 5 is a section of the crownliead,sho\ving the beam rem ved and the clevislinks properly locked.

The presentinvention has relation to plowelevises designed and calculated to be attached to the front or forward end of a plow-beam; and its nature consists in the different parts and combination ofparts hereinafter described, and particularly pointed out in the claims.

Similar letters of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, A represents the crown-head, which is substantially of the form shown in the drawings, and is securely attached to the forward end of the beam A by means of the lips or extensions a a and the clamping-bolt a. The crown-head A is pro vided with the cogs or teeth I), which cogs or teeth are formed in the side flanges, B, and are located substantially as shown in the drawings. The inner faces of the flanges B fit against the side faces of the beam A, thereby assisting in holding the crown-head A in proper position on the end of the beam A. The clevis-link O is substantially of the form shown in the drawings, and is attached to the beam A by means of the clamping-bolt c. This clevis-link O is provided with the cogs or wards d, which are located upon the inner faces of said clevis link, and are for the purpose of engaging the cogs or teeth I), and also adjusting the clevislink, either up or down, within the limits of the cogs or teeth I).

For the purpose of locking the clevis-link C at'any desired point. the locking block or plate D is provided, which may be substantially of the form shown in Fig. 2, and, as shown, is provided with the side lug or car, (2, located in front of the aperture (1", and is for the purpose of fitting in the elongated slot (1, thereby locking the clevis link 0 in proper position.

In use, when it is desired to change the lo cation ofthe clevislink O, the nutE is loosened sufficiently to permit the lug or car to be withdrawn from the elongated slot (1", when the clevis-link C can be forced backward, thereby disengaging the front or forward end of said clevis-link, when the same can be adjusted as desired, and the loeki ng block or plate D placed in proper position. The front or forward end of the clevis-link C is provided with the inwardly-projecting lug or pin F, which may be substantially of the form shown in the drawings, and is for the purpose of receiving the rear portion of the double-tree clevis G, as shown in Fig. 4, thus providing a bearingpoint for the double-tree clevis that will permit the plow to keep a perfectly straight line, and will not cause the plow to vibrate by reason of any vibration of the double-tree.

For the purpose of keeping the double-tree clevis on the lug or pin F when draft is applied, the fins or extensions Hare located substantially as shown, so as to cause said donbletree clevis G to automatically adjust itself on the lug or pin F. The elovis link O is provided upon one side with the extensions or shoulders D, which are for the purpose of abutting against the bolthead c, and thereby assisting in holding the clevis-link O in proper position. It will be seen that the clevis-link G will be securely held in proper position by means of the extensions or shoulders I), independent of the locking-block D.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the plow-beam A, having crown-head A, provided 011 its inner surface with a vertical series of rearward-projecting cogs, b I), of the clevis-link O, adjustably secured to said plow-beam and provided with forward-projecting lugs d d, to engage ICO ' the cogs on the inner surface of the crownhead, substantially as described.

2. The combination, with the plow-beam A and clevislink 0, having cogs d d and clongated slots (1 d of the bolt 0 and lockingplates D D, having apertures d and side lugs, d, substantially as described.

3. The combination, with the plow-beam and attached crown-head A, having a vertical series of rearward-projecting cogs, b b, of the clevis-link 0, having forward-projecting lugs d d, to engage said cogs, and provided with elongated slots d" d and shoulders D D, and the bolt a, substantially as described.

4. The combination, with a plow-beam and attached crown-head having rearward-projecting cogs I) b, of the clevislink 0, having elongated slots d cogs d, and pin F, formed with side fins, H, substantially as described.
